Further, in the thickness dimension t of the protruding portion 40, the thickness dimension t1 of the root portion is set to 1.3 mm, and the thickness is gradually reduced from the root portion toward the tip. And the thickness dimension t2 of the front-end | tip part is formed in 1.0 mm.
When the decorative member 20 contracts in a state where the lower end surface 10a of the window plate 10 is in contact with the projecting portion 10, a contraction force acts on the projecting portion 40 due to the difference in contraction amount between the window plate 10 and the decorative member 20. The part 40 is thinner and easier to deform than the outer wall part 21. Therefore, the projecting portion 40 can be deformed or broken near the root portion or near the tip before the outer wall portion 21 to absorb the shrinkage of the decorative member 20, thereby affecting the outer wall portion 21. Absent.
Further, in the first embodiment, the protruding length dimension L in the plate thickness direction of the window plate 10 of the protruding portion 40 is set to a length that is half or more of the plate thickness dimension T2 of the window plate 10.
In the first embodiment, the relationship of “L≈T2” is set.
Moreover, the protrusion part 40 is integrally molded simultaneously with molding the decorative member 20 from a polymer material by injection molding.

  Moreover, in this Example 1, even if the protrusion part 40 fractures | ruptures in the base part vicinity, it shows in FIG. 8 so that the decorative surface of the outer surface of the outer wall part 21 and the side wall part 23 may not be affected. As described above, the outer wall portion 21 and the side wall portion 23 are formed so as to protrude from the lower ends of the outer wall portion 21 and the side wall portion 23 in the direction of closing the groove portion 24 from a position higher by the height dimension H.

The decorative member of the vehicle window plate according to the first embodiment is configured as described above.
Therefore, when attaching the decorative member 20 to the window plate 10, as shown in FIGS. 2 and 3, the position where the rear end portion of the window plate 10 abuts the window plate end surface rib 26 in the groove portion 24 of the decorative member 20.

Can be satisfactorily positioned in the vertical direction.

In the first embodiment, the protrusion 40 has a rigidity capable of supporting the weight of the window plate 10. Thereby, even if the adhesive 15 is not solidified in the initial state in which the window plate 10 is bonded to the vehicle body panel 1 with the adhesive 15, the weight of the window plate 10 can be favorably received and supported by the protruding portion 40.
For this reason, it is possible to prevent the window plate 10 from being unintentionally displaced (lowered).

Moreover, in this Example 1, the protrusion part 40 can ensure the rigidity of the protrusion part 40 by forming in the flat part shape which two sides couple | bonded with the wall part, the outer wall part 21 and the side wall part 23 here. it can.
Further, since the protruding portion 40 is not joined to the inner wall portion 22 and forms a free end, the protruding portion 40 is easily deformed on the side forming the free end.
The protruding portion 40 may have two sides connected to the inner wall portion 22 and the side wall portion 23, or one side may be joined to any one of the wall portions.

  Further, in the first embodiment, the decorative member 20 is molded from the polymer material, and at the same time, the protrusion 40 is integrally formed, so that the trouble of separately manufacturing the protrusion 40 and fixing it to at least one wall portion can be saved. it can.

In addition, this invention is not limited to the said Example 1, In the range which does not deviate from the summary of this invention, it can also be implemented with a various form.
